Not only does it switch on our anti-aging genes, but it also activates the immune system, repairing damaged DNA and clearing away injured cells. It also promotes metabolic flexibility, mental clarity, and sustainable energy levels. Today, I talk with Cynthia Thurlow about how fasting works, identifying the type of fasting that is best for you, and special considerations for women interested in fasting. Cynthia Thurlow is a nurse practitioner, author of the bestselling book Intermittent Fasting Transformation, a 2x TEDx speaker, with her second talk having more than 14 million views, and the host of the Everyday Wellness podcast, a consistent top iTunes podcast in Nutrition. With over 20 years of experience in health and wellness, Cynthia is a globally recognized expert in intermittent fasting and women’s health and has been featured on ABC, FOX5, KTLA, CW, Medium, Entrepreneur, and The Megyn Kelly Show.
